Electron-capture cross section at near-thermal collision energies for Si{sup 4+}+D
- Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831-6372 (United States)
Using a merged-beams technique, absolute total electron-capture cross sections have been measured in the thermal energy regime for collisions of Si{sup 4+} ions with neutral D atoms. State-of-the-art molecular-orbital coupled-channel calculations for the Si{sup 4+}+H(D) systems are compared to the measurements on an absolute scale. Both the existence of a surprisingly large kinematic isotope effect and an observed sharp low-energy increase of the cross section are attributed to trajectory effects due to an attractive ion-induced dipole. {copyright} {ital 1996 The American Physical Society.}
